Inherited Skin Disease in the Persian Cat

Feline Idiopathic Seborrhea

Persian cats are known to inherit a disorder called idiopathicseborrhea. This primary skin disease leads to overproduction of an oily, waxy substance by the skin glands, which clumps in the fur and causes a bad smell.

Though often seen in Persians, seborrhea can affect various breeds of cat and typically in the same way -- the skin becomes red and irritated, which leads to scratching and further cellular damage.

Symptoms and Types

There are two common forms of seborrhea: seborrhea sicca, in which the skin becomes more dry and flaky; and seborrhea oleosa, in which the skin becomes more oily. Most animals with inherited seborrhea have a combination of the two forms.

Seborrhea in cats tends to affect the skin along the back and around the eyes and ears. It also causes irritation in those areas where the skin folds, such as in the armpits; on the underside; around legs; and on the face, feet, and neck.

Causes

In the primary (also called idiopathic, or unknown) form of the inherited disease, the cause of seborrhea is unknown. In the case of a secondary seborrhea, the cause may be due to an underlying problem, which can include:

Parasites

Fungal infections

Allergies

Dietary problems

Endocrine disorders

Obesity

Diagnosis

Your veterinarian will do a physical examination and check your cat for any disease that may cause a secondary seborrhea. Tests that may be used include:

Chemistry panel

Complete blood count (CBC)

Hormone analysis

Skin scraping

Bacterial culture

Fungal culture

Skin biopsy

Once every other potential cause of the condition is ruled out, a diagnosis of primary idiopathic seborrhea can be made. If your cat is a Persian, the vet will have an even easier time making the diagnosis, as they are prone to idiopathic seborrhea.

Treatment

As it is not possible to cure idiopathic seborrhea, treatment will mainly focus on controlling the condition. This may include using a combination of shampoos and conditioners to control the amount of oily buildup and calm the itchy skin. Your veterinarian may also prescribe oral vitamin or fatty acid supplements.

If your cat contracts a secondary infection, other therapies such as antibiotics (oral and topical), antifungals, and sometimes allergy medications may be necessary.

Living and Management

Keep your pet clean and well hydrated. This will help control the condition and reduce the chances that a secondary infections develop. In addition, schedule regular follow-up exams with your veterinarian to monitor the cat's skin condition.
